Someone should make some! especially for those bit draggers out there *beams in pride* like red red yellow green for the starting lights for the bit dra-g races. sorry its late if u cant understand me.
$5 a pair at Wal-Mart. They're in the X-mas section near the little ceramic houses. They have red/yellow/green LED's in them and the pair of them cycle in sequence. red-yellow-green-yellow-red. When one is red, the other is green-vice versa. They are both on yellow at the same time. They only stay on each color for about one second.
